Lukjan rx3214 Manual Volume Damper 14 Inches Dual-pin

Product Description

The LUKJAN rx3214 is a 14-inch manual volume damper designed for regulating airflow in residential and light commercial duct systems. The dual-pin blade design allows technicians to set and lock the damper blade position, providing reliable zone balancing without drift over time. At 14 inches in diameter and just 1 inch in depth, this unit fits into standard round duct runs with minimal clearance requirements. HVAC contractors and sheet metal installers use this damper during new construction, system retrofits, or rebalancing work where precise airflow control is needed across multiple zones.

The rx3214 is suited for round duct applications in forced-air heating and cooling systems. Its 14-inch size addresses larger trunk or branch runs where significant airflow volumes must be controlled. The manual adjustment mechanism makes it appropriate for static zone configurations where airflow is set during commissioning and does not require frequent repositioning. Light commercial installations such as small offices, retail spaces, and multi-zone residential builds are common deployment environments for this damper size.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling unit and confirm the system is de-pressurized before cutting into existing ductwork. The damper should be inserted into the duct run and secured with sheet metal screws and duct sealant per local mechanical code requirements. Set the blade position during system commissioning and verify airflow balance across all zones before closing out the job.
